ECCENTRIC.

SPECIFICATION forming part of Letters Patent No. 272,511, dated February 20, 1883.

Application filed January 12, 1883. (No model.) 1

.To all whom fit may concern 1 Be it known that I, RUSSELL RrcHARrsoN ANGELL, of Janesville, in the county of Rock and State of Wisconsin, have invented certain .5 new and useful Improvements inV Eccentrics; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as-will enable others skilled in the art to which it pertains to make and use the same'.

My invention relates to an improvement in eccentrics, the, object of the same being to provide simple and effective means for adjusting the eccentrics relative to the shaft, whereby the amountordegree of eccentricity isincreased or diminished as circumstances demand; and with this end in view my invention consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of the inner face of theeccentric. Fig. 2 is a similar view ot' the outer face thereof. Fig. 3 is a vertical sectional view, and Fig. 4 shows the several parts detached.

A represents a small metallic disk adapted to be secured eccentrically to a shaft, or secured to or formed integral with a sleeve, B, into which latter one end of a shaft is adapted to be secured. This disk or' eccentric A is adapted to rest in a recessl or circular depression formed to one side of the geometric center ofthe disk O, and is provided with a lug, a, adapted to enter one of a series of holes, b, formed in the said disk O The disks A and G are held together by the screw D, which latter passes through the disk O a little to one side ofthe center of the same,

l and enters the disk A directly in its center 4o and forms the axis on which it turns. The

holes b in the disk C are formed in the arc of Y a circle around the screw D at suitable intervals apart, and the lug a is adapted to enter one of the said holes, and` together with the screw I) hold the two disks A and C in proper relative position.

The disk A snugly rests within the recess in the disk O, and when the screw D is loosened, so as to enable the lug ct to be drawn from the holes in the disk 0, is free to be turned there- 5o on so as to bring the sleeve B nearer to or fartheraway from the geometric center of the disk O, and consequently decrease or increase the throw or movement of the eccentric-arm E and the eccentric-rin g H. 5

Suppose that the parts composing the eccentric are adjusted to give the least amount of throw or movement, and it is desired to increaseA the .amount of said movement. The

screw D is loosened sufciently to enable the 6o lug t to be withdrawn from the hole b in the disk C. The sleeve B, with its disk A, is then turned in the vdisk C until the desired degree of eccentricity is reached. .The disk A is then pressed inward,and held therein by the lug a wherein an'adjustable eccentric is employed.

It is evident that slight changes in the construction and relative arrangement of the several parts might be resorted to Without de- 8o parting from the spirit of my invention, and hence I would have it understood that I do not limit myself to the exact construction of parts shown and described, but consider myselfl at liberty to make such changes as fairly 8 5 fall Within the vspirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patel1i3,iS- 9o l. The combination, with a disk, of a second disk adjust-ably secured eccentrically within the first disk. ,Y
